Specification of Letters Patent.

Patented Feb. 17,1920.

Application filed April 5, 1919. Serial No. 287,736.

To all whom t may concern:

Be it known that I, WEBSTER L. MARBLE, a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented certain new and useful Improvements in Detachable and Interchangeable Butt-Pieces for Firearms, of which the following is a specification.

Experienced shooters consider it extremely important that a certain fixed length of reach between the shoulder and the trigger of a gun be maintained. According to weather conditions and localit a hunter, or other shooter, changes from light to heavy clothing, or vice versa, .which varies the length of reach between the shoulder and the trigger, and tends to disturbthe handling of the piece, the ease of the shooter, and the proper trigger pull.

The present invention `has for its object the provision of means whereby the shooter may compensate for differences in reach when changing from light to heavyclothing,

.or the reverse.

lIVith .the foregoing object in view, the invention contemplates the vprovision of novel detachable and interchangeable butt pieces or plates, with or without a recoil pad, for arm, whereby a thickness, with or cushion, may be to the butt end of butt piece, of the proper without as recoil pad or quickly and easily applied the stock to afford the requisite length of the Vgun stock to enable the shooter to meet varying conditions due tochanging from light to heavy clothing, and the reverse.

My invention consists, first, of a lire arm whose stock is provided with attaching .means at its butt, in combination with detachable and interchangeable butt plates or pieces, with or without recoil pads or cushions, whereby a butt plate or piece of the desired thickness may be applied to the stock; second, a fire arm whose stock is provided with a novel attaching butt member which is constructed so that the usual screws which hold the ordinary or common'butt plate, may, on the removal of the ordinary or commonbu-tt plate, be used for the attachment thereof to the stock, in combination with detachable and interchangeable -buttpiecesor pads as above set forth; third, a novel attachable auxiliary Jr supplemental butt piece for the stock of a fire arm, comprising a butt plate of improved form to be directly connected to the stock of the lire arm, and a pad, cushioned or rigid, having an improved detachable connection -with the plate, whereby on connecting the plate to the butt end of the stock, any pad may be attached to the plate or removed therefrom quickly and easily for the substitution of another pad o-f different thickness; fourth, the invention comprises those specific embodiments of structure and ad. ptation and combination of parts set forth fully hereinafter.

The embodiments of the invention which are shown in the accompanying drawings and are speciiically described, are illustrative, instead of restrictive, of the scope of the invention as I do not limit myself to specific features except where they are speciiicall recited' in the ap ended claims.

A portion of the stock of a gun is shown at l, the original or ordinary butt plate, commonly used on guns, having been removed but the screws 2 by which said original butt plate was held, being allowed to remain for the purpose of securing to the stock the plate 3 which forms a part of the present invention.

Referring first to Figs. 1, 3, 5, 7, 9, the substitute butt plate 3 is preferably of metal, although I do not limit ticularmaterial employed. This plate has an undercut or dove-tailed rib 4 extending longitudinally thereof from one end 5 to a point which is short of the other end of the plate 3, being there provided with a shoulder 6. Concavities 7 and 8 are provided in the face of the rib 4 and the slots 9 and 10 extend through the plate 3 and lie in the major aXis thereof parallel with the rib. The shanks of the screws 2 pass through the slots 9, 10 and the heads lie in the concavities 7 and 8 below the upper face of the rib 4. By the provision of the slots 9 and 10, the screws, which hold the original butt plate, may be used for securing my improved plate 3, as considerable variation between the screws on different stocks is thus provided for; consequently, no alteration in the stock of the gun, nor the use of additional attaching devices or screws is necessary in applying my improvements to the stock of any fire arm unless the original butt plate is taken oi.

The rib 4 also has cavity 11 which is partly in the form of a slot. A stout locking leaf spring 12 provided with a bent portion or shoulder 13 lies in the concavity 11 and has one end Secured at 14. This locking leaf spring is employed for securing the attachable and interchangeable pads to the butt plate 3.

In Figs. 1, 2, I have shown attachable and interchangeable pads 15 and 16 of different thicknesses, either of which may be applied to the plate 3 and rib 4 and used as a supplemental butt piece, of the desired thiclc ness, according to the requirements of the shooter. Except for the diderence of thickness, these pads are of the same construction. They are shown as being provided with a recoil cushion 17 which may be of any well known, or preferred construction. The pads Shown in Figs. 1, 2, 4, 5 have a hard rubber or fiber plate 18 to which the cushion 17 is suitably secured. The rigid plate 18 is provided with recessed portions in which lies metal reinforcement 19 which is provided with an undercut or dove-tailed channel 20, opening at one end 21 through the end of the plate 18 and at the other end being provided with a shoulder 22 located inwardly from the end of the plate 18. 'The reinforcing metal member 19 constitutes a wear plate which prevents chipping for abrasion of the hard rubber or fiber plate 18. The reinforcing or wear plate I19 may be secured to he' plate 18 by any suitable means.

a longitudinal conn The undercut or dove-tailed chanmyself to the paru nel 20 is of a form and proper dimensions to snugly fit, and being adapted to freely slide onvthe rib 4 and against the face of the KYplate 3; and the shoulder 22 finally comes into engagement with the shoulder 6. The reinforcing member or plate 19 has a cut-out or open portion 23 whose ends are provided with upturned ianges or shoulders 24, one` of which is so positioned that when the shoulders 6 andg22 are in engagement, the locking end 13 of the spring within the opening 23 and enga es the advance shoulder 24 thereof, there y locking the parts together. A11 aperture 25 is provided in the cushion 17, said aperture intersecting the opening 23 and being located above the lockin end of the spring 12 when the parts are loc ed together. By inserting a nail, pencil, match, or other suitable device through the hole 25, the locking end of the spring may be depressed into the concavity 11 to release the spring from the shoulder 24 so thaty the pad, 15 or 16, may be readily unlocked.

Referring to Figs. 10, 11, 13, 15, the plate 3, rib 4, slots and concavities, and manner of securing the plate 3 to the stock by the screws 2, is substantially the same as heretofore set forth. The shoulder 6a may be rounded instead of square, as previously described. The locking spring 12a is reversed in position but otherwise substantially the same as spring 12.

In Figs. 10, 12, 13, 14 there is shown a solid detachable supplemental butt piece or pad 26 which may be of fiber, or hard rubber, or, Vmetal might be used in the thinner pads. The pad 26 is shown as made of hard rubber or fiber and has a longitudinally eX- tending dove-tailed or cut-out slot 27 ending in a shoulder 28, the latter corresponding to the shoulder 6a'. The slot or cut-out portion 27 is of a size and form adapting it to fit thev rib 4. A wear plate 29 is suitably secured to the inner face of the vpad 26 and has a shoulder 30 to enga e the shoulder 13*al on the spring 12 to loc the pad to the plate 3. A recessed portion 31 accommodates thehead of the spring. An4 aperture or hole 32, which extends through the pad 26, is adapted to receive a nail, match, or other suitable implement end of the spring may be depressed and forced-out of engagement with the shoulder 30.

lThe plate 29 may be secured in different ways. In Figs. 16, 17 I have shown two different forms of securing means for the plates 29 and 29a'. The platey 29 has a prong 33 which passes through the hole 32 and is clenched down. Said plate has other prongs 12 is received so that the locking 34 at its other end which enter the pad 26. p

The plate 29 isl shown `in its relative position Ain Figs. 10, 1,2, 14 and 16.

The platemay be reversed as to position,

as shown at 29a, Fig. 17, and have its arranged in, or adjacent, hole 32, and its other prong 36 entered into the pad.
